+ *
+ *  The behaviour of this driver can be altered by setting some parameters

+ *
+ *  The following parameters are adjustable:
+ *
+ *	bus0	These four arguments can be arrays of
+ *	bus1	1-8 unsigned integers as follows:
+ *	bus2
+ *	bus3	<id>,<sda>,<scl>,<udelay>,<timeout>,<sda_od>,<scl_od>,<scl_oo>
+ *
+ *  where:
+ *
+ *  <id>	ID to used as device_id for the corresponding bus (required)
+ *  <sda>	GPIO pin ID to used for SDA (required)
+ *  <scl>	GPIO pin ID to used for SCL (required)
+ *  <udelay>	signal toggle delay.
+ *  <timeout>	clock stretching timeout.
+ *  <sda_od>	SDA is configured as open drain.
+ *  <scl_od>	SCL is configured as open drain.
+ *  <scl_oo>	SCL output drivers cannot be turned off.
+ *
+ *  See include/i2c-gpio.h for more information about the parameters.
+ *
+ *  If this driver is built into the kernel, you can use the following kernel
+ *  command line parameters, with the same values as the corresponding module
+ *  parameters listed above:
